Product Information

EXPAND YOUR FACTORY DME’S CAPABILITIES WITH BOOTMOD3 REV2


The bootmod3 REV2 Controller connects additional performance hardware to the factory engine computer in supported S58 and Gen 2 B58 vehicles. It gives your tuner access to extra sensor signals and control outputs while keeping the calibration within the vehicle’s DME.

Designed for builds using additional fuel delivery or advanced boost-control hardware, REV2 works with bootmod3 CustomROM V2 to bring these systems together through one tuning platform.

bootmod3 CustomROM V2 and compatible DME tuning access are required. A standard bootmod3 licence or previous DME unlock alone does not confirm compatibility.


WHAT IS THE BOOTMOD3 REV2 CONTROLLER?


REV2 is a hardware interface for the factory DME. It passes sensor information to the DME and operates connected components according to the tuning strategies configured in bootmod3.

Calibration remains in the DME and is managed through the bootmod3 Map Editor. There is no separate REV2 fuel or ignition map to tune. The controller also has Wi-Fi for firmware updates through the bootmod3 app.

FLEXRAY & DIRECTPWM INTEGRATION

FlexRay provides the communication link between REV2 and the DME. Its scheduled static-segment messaging supports consistent timing for control commands.

DirectPWM uses an existing DME output to send a pulse-width signal through the vehicle wiring to REV2. The controller reproduces that signal at the connected output. This control method is available for sequential port injection and a compatible pneumatic boost-control solenoid, with configuration stored on the DME.




REV2 FEATURES & FUNCTIONS


WHAT CAN REV2 CONTROL?

  • Sequential port injection with up to eight high-impedance injectors
  • Pneumatic wastegate boost control using a compatible MAC solenoid
  • Secondary fuel pumps, including supported brushed and brushless arrangements
  • Nitrous solenoid control
  • Water/methanol injection with independent pump and solenoid outputs
  • Line-lock solenoid operation integrated with supported factory controls
Injectors, pumps, solenoids and other connected hardware are additional components. The required wiring, relays, sensors and calibration depend on the installation.

SENSOR INPUTS & MONITORING

REV2 provides eleven sensor inputs. Available monitoring includes:

  • Fuel pressure and coolant pressure
  • Nitrous bottle pressure and exhaust back pressure
  • Two exhaust gas temperature channels
  • Turbine speed
  • Ethanol content and fuel temperature from a compatible flex-fuel sensor
  • Water/methanol flow and tank level
  • Laser ride height for logging
Sensor signals are calibrated and interpreted by the DME through the bootmod3 Map Editor. The controller relays the raw signals rather than performing ethanol analysis itself. Additional sensors are sold separately unless specifically included in the selected package.

INTEGRATED CUSTOMROM V2 SAFETIES

CustomROM V2 allows the tuner to configure fault detection and responses for the connected systems. These can include fuel-pressure, coolant-pressure, overboost, knock, injector, ignition and communication faults.

Responses are configured within the DME and can include output cuts and load or torque limits. Their operation depends on the installed sensors, correct calibration and the tuner’s settings.


WHAT’S INCLUDED?


The REV2 base package brings together the controller, protective enclosure and mounting hardware, along with the wiring harnesses and 7 bar MAP sensor for integration with your vehicle’s factory DME. The following components are supplied as standard:

  • REV2 controller board
  • IP66-rated polycarbonate enclosure and mounting bracket
  • Main motorsport-grade wiring harness
  • Flex-fuel sensor sub-harness, without an ethanol sensor
  • Pressure-sensor sub-harness
  • 7 bar / 100 psi MAP sensor and the supplied plug-and-play harness for the factory intake-manifold sensor connection
The MAP sensor connects to the vehicle harness and is calibrated in the DME. It is not a built-in REV2 sensor.

OPTIONAL HARDWARE

Depending on your build, additional hardware may include a 10 bar / 150 psi absolute fuel-pressure sensor, engine-bay flex-fuel components with an ethanol sensor, a coolant-pressure sensor kit, or an intake-manifold boost take-off fitting.

A complete port-injection installation also requires suitable injectors and fuel-system hardware. Injector flow and latency data must be available for calibration. Confirm your existing hardware with SouthernBM before ordering additional components.


SUPPORTED VEHICLES & SOFTWARE REQUIREMENTS


bootmod3 currently lists support for S58 and Gen 2 B58 engines.

S58 applications include the BMW G87 M2, G80/G81 M3, G82/G83 M4 and F97/F98 X3 M/X4 M. Gen 2 B58 applications require confirmation of the engine version, DME software and harness suitability before ordering.

Support should not be assumed for Gen 1 B58, newer B58 generations, S55, N55, B48 or MINI applications. A shared model badge or chassis does not confirm REV2 compatibility.

The DME must be capable of running the required CustomROM V2 software. Previously unlocked DMEs may need additional work or an update. Send us your VIN and bootmod3 DME information so we can confirm the requirements for your vehicle.


INSTALLATION & TUNING


REV2 requires installation and custom calibration appropriate to the hardware fitted. The controller is not an off-the-shelf tune and does not include a bootmod3 software licence, custom tuning or DME unlocking.

Contact SouthernBM to discuss hardware suitability and installation requirements for your build before ordering.


FREQUENTLY ASKED QUESTIONS


Does REV2 replace the factory ECU?

No. The factory DME retains the tuning calibration and control strategies.

Do I need a separate flex-fuel controller?

A compatible ethanol sensor can connect through the REV2 harness, with analysis handled by the DME. Confirm the fuel-line components and sensor arrangement required for your installation.

Is everything shown in the photos included?

Refer to the included-components list and selected package. Optional sensors, flex-fuel components and other accessories may be shown for illustration.

Will REV2 increase power by itself?

Results depend on the engine hardware and custom calibration. REV2 enables control of additional components; it does not provide a fixed power increase on its own.


IMPORTANT INFORMATION BEFORE YOU PURCHASE


Confirm the engine generation, CustomROM V2 support, DME tuning access and required hardware before ordering. Individual feature availability depends on the vehicle, software and installation.

Motorsport functions and vehicle modifications must be used in accordance with the applicable rules for the intended use.
